The inquest into recent Champions League games has centred around the legitimacy of penalties being given or not.

Hleb's, Ronaldo's and Babel's spring to mind. But being overlooked is the Eto'o penalty in the Nou Camp which should have been given but wasn't because he stayed on his feet after he was fouled by Rio Ferdinand. Had he gone down it was a cast-iron shout.

Why can't the same rule apply inside as outside the box, when the referee allows play to go on for a few seconds but can bring it back if he sees he's given no advantage?

The alternative is what must surely be going through Eto'o's head now. If I get clipped again at Old Trafford I'm going down. By penalising honesty we encourage dishonesty. Is that too difficult a concept for UEFA to take on board?
